Dhtmlxscheduler Error with Multi Day

I can’t get the multi day attribute to work, when I set it to true IE comes up with error invalid argument. It also doesn’t appear in the option for scheduler.config in visual studio

can you provide your code, or demo where it can be tested?

Sorry just a correction multi-day does work but some weeks have to many events running for multiple days and i presume it cant display them all therefore appears blank. Is there any way to restrict the size of the top section where they appear so the weekly calendar always appears and you can scroll through the multi day events ?

I’ve got it to work by hardcoding a height into the javascript file and setting an overflow vis css.
